You'll need a larger air meter which is matched to your injectors and, speaking of injectors, 24# may not be large enough for your build. They max out at about 345 HP.

Google "compression ratio calculator". It will give you dozens of them.

Is your automatic an E4OD or an AOD? The E4OD will not work without a computer.

Talk to the techies at Motorvation. They will recommend a MAF meter compatible with their PCM and will also probably be able to size the injectors based on your build info.

With an AOD, yes. It has no interface with the PCM.
Whether you should or not is entirely a different matter. There is so much EFI stuff out there for the 5.0 Mustangs and 90+% of it is directly applicable to trucks that it seems like a waste of time, money and effort to step back to carburetion and an old-style ignition.

There's also the matter of the AOD not being the strongest tranny that Ford ever built. The 2 piece input shaft is a known weak point. Count of some major tranny surgery as part of a performance rebuild.
